Description:

Abstract:

This dataset includes zooplankton displacement volume sampled in Glacier Bay National Park during summer of 2004. Zooplankton were sampled with a multinet with a 0.5 m^2 mouth opening and 335 µ mesh.

Purpose:

The purpose of this data is to estimate the zooplankton displacement volume at stations in glacial fjords of Glacier Bay National Park, Alaska.

Supplemental_Information:

The overarching goal of this work was to compare and contrast the influence of glacier runoff on fjord ecosystems across the Gulf of Alaska. We sought to 1) describe the magnitude and horizontal range of influence of key near-surface physical characteristics associated with glacial runoff in coastal marine waters, and 2) characterize the distribution and response of lower- to upper-trophic level organisms relative to glacially influenced habitat gradients. This dataset is one of several types of data collected concurrently, including physical (conductivity, temperature, and depth (CTD), nutrients) and biological (zooplankton, fish and marine birds) variables from the same sampling locations (detailed in project metadata).

Attribute_Accuracy_Report:

The quality of all data and metadata are reviewed by the USGS as part of its standard internal procedures for quality control and quality assurance. Processed data are reviewed for any outliers or bad data. The difference in sampling and processing methods preclude direct comparison of zooplankton biomass between GLBA and other study regions.

Methodology:

Methodology_Type: Field
Methodology_Description:

Zooplankton were sampled with a multinet that had a 0.5 m^2 mouth opening and 335 µ mesh in in Glacier Bay National Park during summer of 2004.

Process_Step:

Process_Description:

For GLBA multinet samples, bulk zooplankton samples were processed by estimating displacement volume to the nearest 0.25 ml, converting displacement volume to relative wet mass assuming 800 mg cm^-3 (Harris et al. 2000, p 140) and dividing by the volume filtered (m^3).
